Lev Nikolayevich Tolstoy, The Christian Teaching
“ The sin, i.e. mistake, of sexual lust for a person who has chosen the way of chastity, is that he, being able to choose the highest purpose and to use all his efforts to serve God, i.e. for the expansion of love and the attainment of the highest well-being, descends to the lowest level of life, and deprives himself of this blessing.13. For a person who has chosen the direction of procreation, a sexual sin, or a mistake, consists in that, when he deprives himself of having children, or, at least, of family relationship, he deprives himself of the highest benefits of sexual life. ”
